• Composite Power: DL +37 dBm; UL +23 dBm
• RF Gain: Up to 90dB Gain
• Up to eight software selectable non-contiguous sub-bands in any combination (the
number of supported bands depend on the selected bandwidth of each sub-band)
• Individual gain and power settings for each sub-band
• High linear amplification and spectral purity and highly accurate frequency selection
• Excellent out-of-band interference prevention
• Mechanism for tunable rejection of interference from adjacent cellular and paging
frequencies
• SmartALC™ technology:
• Automatically sets optimum gain
• Prevents oscillations and balances coverage
• Intuitive Web management GUI application provides simple setup, monitoring and
control via a local or remote Ethernet connection
• SNMP fault notification
• Wallmount, IP65 (NEMA4) Enclosure.
• MCPA technology supporting top level EVM, ACRR and emission performance

The Smart Automatic Level Control (Smart-ALC) is an innovative algorithm for
automatic repeater gain adjustment. Combined with advanced control algorithms, SALC
is capable of learning the traffic load characteristics and adjusting the Repeater RF Gain
to the desired value.
The repeater’s power amplifier includes power-monitoring circuits with Automatic Level
Control (ALC) that prevents excessive output power while maintaining the power
amplifier linearity.
